ATTACHMENT FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 613,421, dated November 1, 189.

Application filed March 26, 1896. Serial No. 584,983. (No model.)

To all whom it may concern.-

Be it known that I, HUGO C. KRAUSE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Type-Writers, of which the following is a specification.

This invention relates to attachments for type-writers.

The object of the invention is to provide a spacing attachment for type-writers for use in tabulating or billing work which is of simple and improved construction, easily understood and operated, and efficient in operation.

The invention is designed as an improvement on the construction shown, described, and claimed in Patent No. 559,449, dated May 5, 1896, to Fred P. Gorin; and it consists, substantially, in the construction, combination, location, and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.

Referring to the accompanying drawings and to the various views and reference signs appearing thereon, Figure l is a plan view of a construction embodying the invention detached from the machine. Fig. 2 is a transverse sectional view of the same, taken on the line 2 2, Fig. 1. Fig. 8 is a detached broken detail view, in side elevation, illustrating a means through which the paper-carriage feed mechanism is released. Fig. 4 is a longitudinal sectional view taken on the line 4 4, Fig. 1, the frame of the type-writing machine being indicated in cross-sectional outline, showing the connection of the attachment to the paper-carriage and to the carriage-feed release. Fig. 5 is a detached broken detail view, parts beingin section, showing the manner of operating the carriage-feed release.

The same part is indicated by the same reference sign wherever it occurs throughout the several views.

Reference sign A indicates the framework of a type-writing machine; B, the paper-car- 'riage; C, the pivoted rack-bar carried by the paper-carriage and forming part of the usual step-by-step feeding mechanism for the paper-carriage. These several parts may be of the usual or any suitable, convenient, or well-known form of arrangement and of any type of machine, and as these parts form no part of the present invention detailed illustration and description thereof in the present instance are unnecessary.

Reference-letter D designates the frame upon which the operating parts of the spacing attachment are mounted. This frame may be arranged in any suitable or convenient manner with reference to the particular type of machine to which the attachment is to be applied. I have shown the attachment as applied to a Remington machine, and in the form shown, to which, however, I do not desire to be limited or restricted, the frame D forms a base upon which the machine rests, the front and rear cross-bars of frame D being provided with seats 6,.adapted to receive the side frames of the type-writer machine.

Mounted upon or carried by the frame D is a pivot stud or bolt 7, upon which is pivotally mounted to vibrate a bracket 8, upon which are mounted the various parts of the attachment hereinafter to be described and which has suitable connections with the paper-car riage and its feed-release bar. In the particular form shown, to which, however, I do not desire to be limited, the bracket is in the form of a double segment, carrying on one side of its pivot the auxiliary keys and connected on the other side of its pivot to the paper-carriage and release-bar, as above mentioned.

The connection with the pa per-carriage may be effected in any suitable manner whereby the bracket 8 is swung or vibrated upon its pivot coincidently with the movement of the paper-carriage and to a proportionate extent. In the particular form shown, to which, however, I do not desire to be limited, I attach one end of a connection 9 to the rearwardlyextending segment of bracket 8, as at 10, and

connect in any suitable manner the other end of said connection to any convenient part of said paper-carriage, as at 11, Fig. 4. In order to secure the proper lead for connection 9, I may provide suitable guides 12 13 and mount the same adjustably, as by slot 14 and bolt 15, upon the frame of the type-writer, and, if desired, and in order to reduce friction, the guides 12 13 may comprise rollers. By the adjustment of the guides the proper tension may be maintained in connection 9 and slack therein may be readily taken up. In a similar manner the end of a suitable connection 16 is attached at one end to the rear segment of bracket 8 and thence leads over adjustable guides similar in all respects to those above described for connection 9, and the opposite end of said connection is so connected in any suitable manner to the rackbar 0 of the paper-carriage feed mechanism as to be caused to move with the carriage and in addition to cause under suitable conditions the rack-bar to be rocked about its pivots and out of engagement with the ratchetteeth, thereby disconnecting the paper-carriage from its usual orstep-by-step feed mechanism. The special manner of effecting such connection will of course vary with the different types of machines and with the exigencies of the particular machine. I have shown, therefore, a conventional method of such attachment, to which I do not desire to be limited, wherein the end of connection 16 is attached to a crank-arm 17, depending from a rock-shaft 18, said rock-shaft having an oppositely-extending arm 19, arranged to engage when said shaft is rocked with an arm 20, suitably connected to the pivoted rackbar 0 of the paper-carriage feed mechanism. From this construction it will be seen that when a pull is exerted upon connection 16 the shaft 18 is rocked, the arm 20 is depressed by the engagement therewith of crank-arm 19,, and the rack-bar O is rocked out of engagement with the ratchet feed-dogs. It will be distinctly understood, however, that my invention is not limited to the specific form and arrangement of parts, for many variations therefrom would readily suggest themselves to persons skilled in the art and still fall within the scope of my invention, the essential and generic idea of which is that through the actuation of connection 16 the paper-carriage is released from its feed mechanism.

The particular form of connections 9 and 16 is unimportant. I have shown these connections as flexible bands, though it is evident that any other suitable or convenient form may be employed. It will be observed that the ends, respectively, of connections 9 and 16 are carried to that side of the segment of bracket 8 farthest from the side of the machine where said connections are attached to the carriage. From this construction it will be seen that the front segment of bracket S--that is, the segment on the opposite side of pivot-bolt 7will be moved or swung in the same direction coincidently with and proportionately to the movement of the papercarriage.

In order to release the paper-carriage from its feed mechanism when the spacing attachment forming the subject of the present invention is brought into use, it is desirable to provide means whereby the pull on connection 16 may be effected independently of the paper-carriage. Many different forms of mechanism for accomplishing this result may be devised, and therefore, while I have shown an operative embodiment of the idea, I do not desire to be limited thereto. In the particular form shown, instead of attaching the segment or bracket end of connection 16 directly to said segment or bracket, I attach said end to a link 21, carried by one arm of a bell-crank lever 22, pivotally mounted on the bracket 8. To the other arm of said bell-crank lever is connected a pitman or link 23, which in turn is connected to a lever 24, pivoted upon the bracket and suitably and conveniently arranged to be engaged by the auxiliary keys, hereinafter to be described, when said keys are actuated, as will presently be more fully explained. The extent to which connection 16 may be thus actuated may be varied by varying the extent to which bell-crank lever 22 is rocked. This variation may be con veniently secured by varying the point of connection of link 23 with one arm of said lever, as by providing said arm with a series of holes, in any one of which the end of pitman 23 may be secured. From this construction it will be seen that when arm 24 is rocked a pull is exerted upon pitman or connecting-link 23, which in turn rocks bell-crank lever 22, and hence through link 21 efiects a pull upon connection 16, thereby rocking rack-bar C out of engagement with the carriage-feed dogs.

I will now describe the construction and arrangement of parts whereby the arm 24 is rocked to effect a disengagement of the paper-carriage from its feed mechanism. In suitable side flanges 25 26, formed upon a suitable forwardly-projecting part of frame D, is mounted a pin 27, upon which are independently pivoted a series of bars 28, having their forward or outer ends projecting slightly beyond the casing formed by said flanges, and which projecting ends are preferably, though not necessarily, beveled upon the lower and outer edges thereof, as shown at 29. (See Fig. 2.) The bars 28 are mounted independently of each other, except, for compactness and convenience of construction, they may be mounted upon the same pivotpin 27. A spring 30 may be arranged to bear against each of said bars to normally elevate the outer ends thereof. The inner ends of all of said bars are arranged underneath a cross and, preferably, a curved bar 31, carried by or forming part of the pivoted arms 24, said arms in the particular form shown being pivoted upon the sleeve or hub by which bracket 8 is pivotally mounted upon pivotstud 7.

seen that when the forward or outer end of any of the bars 28 is depressed the inner or rearward end of said bar is raised, thereby effecting a raising of cross-bar 31, and hence a rocking of the arm 24, and consequently an actuation of connection 16, thereby releasing From this construction it will be a the paper-carriage feed from its feed mechanism.

Any suitable or convenient construction and arrangement may be provided for manipulating the bars 28 at will. I have shown an operative embodiment of means for accomplishing the desired results, wherein I pivotally mount a series of key-bars 32 in any suitable or convenient manneras, for instance, in a bracket formed upon or carried by frame D--and suitably connect the keybars 32 with the rear ends of the bars 28, there-being as many key-bars 32 as there are bars 28. Each key-bar carries a suitable key, as shown, and it will be understood that the keys are supplemental and additional to the type-keys of the machine, and from the foregoing description it will be seen that by employing the frame D as a supportingbase for the type-writer machine the auxiliary keys are conveniently and handily ar-- ranged at the front of the machine and do not in any manner interfere with the operation of or space occupied by the usual keyboard of the machine. It will also be seen from the foregoing description that when any one of the auxiliary keys is depressed the rear end of its corresponding bar 28 is raised and the front end of said bar lowered, and resulting from this movement of bar 28 the paper-carriage is released from its feed mechanism. Carried by the forwardly-extending segment orportion of bracket 8 is a bar 33, upon which are mounted the adj ustble stops or collars 34. The relative arrangement of stop-bar 33 with respect to the forwardly-projecting ends ofbars 28 is such that when the front ends of said bars are depressed they will form a stop against which the collars 34 will impinge as the bar upon which said collars are mounted is swung or moved with bracket 8, thereby forming a stop for the paper-feed carriage at the required or desired point, since the operation of depressing the outer end of bar 28 also releases the carriage from its feed mechanism and the movement of the bracket 8 and the papercarriage is synchronous.

By adjusting the collars 34 the point at which the carriage is stopped may be regulated and varied at will. As shown, the bars 28 are arranged in close proximity to each other, side by side, and each bar is of a thickness corresponding to a letter-space on the usual spacing-scale of the machine. Therefore from the foregoing description it will be seen that by adjusting the collars 34 upon stop-arm 33 to the required point and by suitably manipulating the auxiliary keys the paper-carriage is released from its feed mechanism and is moved under the'influence of its controlling-spring, and coincidently with such movement rocking said bracket 8 until the stop-collar impinges upon the lowered projecting front end of the particular bar28 which has been actuated, thereby arresting the carriage at the required point-say, for

instance and by way of illustration, at the point 4O of the ordinary spacing-scale. Now suppose it is desired to record a vertical column of figures of varying denominations with all the units falling directly under each other at a point on the page determined by the spacing-mark 40 of thespacing-scale, and the first number of the column to be re corded is of the tens denomination. Then the stop-collar 34 is adjusted to the required point on stop-bar to arrest the paper-carriage at the point 40, when the auxiliary key marked Units is manipulated. Then by pressing the auxiliary key marked Tens the paper-carriage is released from its feed and is arrested at a point one letter-space removed from the spacing-mark 40. The first figure of the number to be recorded is then written with ordinary type, and the ordinary step-bystep feed mechanism of the carriage effects a feed of said carriage into position to record the units figure of the number at the point 40, as previously determined upon. In like manner on the next line the carriageway be released and arrested at a point two letterspaces removed from the point 4O to record the first figure of a number of the denomina tion of hundreds by manipulating the hundreds auxiliary key, and so on for each succeeding line. The provision of several stopcollars enables several columns to be recorded at different points on the same page. The shock and jarin the construction and operation above described is not communicated to the paper-carriage nor to any of the delicate parts of the type-writer mechanism, but is borne entirely by the attachment and is largely taken up in the connections, which, as explained, are preferably flexible between the attachment and thepaper-carriage.

It may sometimes happen that the stop-bar 33 will occupy a position such that a collar 34 thereon offers an obstruction to the depression of a bar 28 just at the time when it is desired to depress said bar, thereby rendering it impossible to depress said bar 28. In order to avoid such a contingency, I so mount the entire bracket that said bracket is movable back and forth, and I bevel off the lower forward corner of the bars 28, as at 29, so that if a bar 28 is depressed and engages a collar 34 by exerting a little pressure the inclined surface 29 will cause the bracket 8 to be moved forwardly, thereby moving the stopbar 33' and the collar 34 thereon out of the way of the bar 28, and hence permitting the actuation of the spacing attachment, as above explained. It will be observed, however, that the forward movement of the bracket 8 under the conditions referred to should be against the action of a spring which would normally tend to return it, to the end that the next stopcollar 34 would impinge upon the depressed end of the arm 28 and so effect an arrest of the movement of the paper-carriage. This idea may be embodied in many different specific forms of apparatus and stillfall within ICC the scope of my invention. I have shown one form of apparatus for accomplishing the desired object, which is designed to be merely an operative embodiment of the idea, wherein the frame D is suitably grooved to receive a movable slide 85, which is formed with or carries the pivot-pin 7, upon which the bracket 8 is pivoted. A suitable spring 37 is interposed between said slide 35 and a stop, as 36, upon frame D. From this construction it will be seen that when bracket 8 is moved forwardly under the influence of the engagement of the inclined surface 29 of a bar 25 with a stop-collar 34 when such bar is depressed the pivot-pin 7 and its slide 35 are also moved, and such movement is against the action of the spring 37. As soon as the bracket 8 has been moved forward a sufficient distance for the obstructing stop-collar to be cleared by the end of bar 28, so that said arm may be fully depressed, the paper-carriage will have been released from its feed, and the movement thereof will cause a swinging motion to be imparted to bracket 8, which will carry the obstructing stop-collar past the depressed end of bar 28, whereupon under the influence of springs 37 the bracket 8 will be moved rearwardly again and into position for the next stop-collar to impinge against the depressed end of the bar 28. In order to permit of this endwise movement of bracket 8 and also to permit of the swinging movement of said bracket and still retain at all times such a rotation of the parts that a manipulation of an auxiliary key will effect a release of the paper-carriage from its feed, I arrange the pivoted arm 31, as shown, so that as said arm partakes of the movements of bracket 8 it will still and at all times overhang the rear end of the bars 28.

The operation will be readily seen and understood from the foregoing description.

IVhile I have shown one operative embodiment of the broad principles of my invention, it will be understood,of course, that the same principles may be embodied in widely-differing specific forms of mechanism. I do not desire, therefore, to be limited or restricted to the exact form,construction,and arrangement of parts shown and described; but
